Samsung pathetic service

I posted 3 weeks ago. I was given a 1k voucher from Samsung when I upgraded my phone and ordered a case for my phone online. I was sent the wrong thing. I chatted online with a consultant by the name of trecia who arranged a return the incorrect item was uplifted from my residence but after that no correspondence has been forthcoming regarding whether I would be allocated a new voucher or sent the correct item. I have been trying since December via live chat and email but am just being ignored. After my last post on hellopeter they called me to check if someone had resolved my issue but after that no one has been in contact. They say they have phoned but I would like to correspondence via email with them as I cannot take calls during working hours due to the nature of my job. Very pathetic service on Samsung behalf. It's nore than 4 months now and still hasn't been resolved
